Everyone involved in the project maybe, but not everyone interested in "a block device for HA clusters". And you don't want to turn them of by using terminology to explain terminology, especially when it's misleading. Many OpenSource projects fail merely for this reason. > And it is self > explanatory because it's an art term for a well defined concept which > forms one of the building blocks of the nomenclature used in clustering. > Even if you're not familiar with clustering terminology, the definitions > are easy to find via search engines. > > If you want to find useful quibbles, the term synchronously is wrong: > DRBD is capable of both synchronous and asynchronous replication. Ok, so maybe change the description to reflect this capability. Something like: DRBD is an independent, synch/async replicated block device.
